【摘 要】目的：分析不同分型肺水肿患者的X线特征性表现，以提高临床诊断率，减少漏诊误诊率。方法：回顾性分析2008年1月—2010年1月收集的50 例肺水肿患者的临床资料，按不同病因分类，分析总结其X线特征性表现。结果：心源性肺水肿30 例，胸部X线片示肺血管纹理增粗模糊，两肺部“蝶翼征”、支气管“袖口征”等特征性X线征象；非心源性肺水肿20例，其中急性呼吸窘迫综合征11 例，胸部X线片早期表现为肺外周肺野弥漫性肺泡实变影，随着病情的进展，病变融合，整个肺野透亮度降低，出现“白肺征”；神经性肺水肿9例，X线表现为肺部“雾霭征”。结论：根据患者的临床表现、病史，并结合肺部X线特征性表现即可诊断肺水肿。

    【Abstract】Objective：analysis of different type pulmonary edema characteristic X-ray performance to improve the diagnosis rate, reduce the misdiagnosis rate. Methods：A retrospective analysis of 20,068 in January -2010 collected on Jan. 50 cases of pulmonary edema in patients with clinical data, classified according to different causes, analyze and summarize the performance of its characteristic X ray. Results：30 cases of cardiogenic pulmonary edema, chest X ray film showed pulmonary vascular thickening fuzzy texture, the two lungs "Dieyi sign" bronchial "cuff" sign and other features of the X-ray findings; non-cardiogenic pulmonary edema 20 cases, including acute respiratory distress syndrome in 11 cases, chest X-ray films showed early peripheral lung field diffuse pulmonary alveolar opacities, as the disease advances, disease fusion, through the decrease in brightness throughout the lung fields, a "white lung sign "; neurogenic pulmonary edema in 9 cases, X-ray findings of lung" sign mist. " Conclusion：The clinical manifestations, history, combined with the performance of the lungs characteristic X ray to diagnose pulmonary edema. ......
